The oils and chromatographies were obtained by hydrodistillation through external partnerships. While the antifungal activity of Baccharis dracunculifolia and Pogostemon cablin oils laying out a mycelial disc of F. graminearum. The scavenging activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. As a result It was obtained the constitutions of essential oils mainly monoterpenes with 32.5 % of camphor in the Rosmarinus officinalis oil, 47 % of thymol in Thymus vulgaris, 31.5% of patchoulol in Pogostemon cablin; and esters with 40.1% of lanalin acetate in the Lavandula angustifolia oil. In the native plants oils the composition was basically of sesquiterpenes. Such as 17.58% of cis trans nerolidolin the Baccharis dracunculifolia oil; 31.6% of germacrene B in the lemon balm; 16.1% α-selinene in the Psidium guajava oil and 18.6% of α-bergamotene in the Schinus terebinthifolius.. The antibacterial activity of Thymus vulgaris oil has shown the most effective results, with minimal inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of0.195 e 1.56 µL.mL-1 against S. aureus; and 0.195 e 50 µL.mL-1respectively for S. enteritidis; and for E. coli, the MIC was 0,390 µL.mL-1and MBC 0.780 µL.mL-1 and for P. aeruginosa 0.780 and 12.5 µL.mL- 1.The antifungal activities were determined against F. graminearum with Pogostemon cablin (8.0 μL.mL-1) during the period of 96h, It has inhibited 80.0% of the fungus. The antioxidant activity of the Pogostemon cablin essential oil was higher than the others with 12.08 µmol trolox/mL-1 radical scavenging activity. Based on this study, It is suggested that oils as Lavandula angustifólia, Thymus vulgaris, Rosmarinus officinalis, Baccharis dracunculifolia, Psidium guajava and Schinus terebinthifolius, can be used against infections caused by S. aureus, E. coli, S. enteritidis and more closely by P. aeruginosa. Also it was found out that Pogostemon cablin oil may serve as an antifungal agent against the phytopathogen F. graminearum. Moreover, the thyme oil can play an important antioxidant activity. Pela crescente utilização das plantas medicinais e óleos essenciais na prevenção e tratamento de enfermidades, embasados nas propriedades antibacterianas, antifúngicas e antioxidantes é que objetiva-se com o presente trabalho identificar a composição e atividade antioxidante dos óleos essenciais de Lavandula angustifolia, Pogostemon cablin, Rosmarinus officinalis, Thymus vulgaris, Hedyosmun brasiliense, Psidium guajava, Baccharis dracunculifolia e Schinus terebinthifolius, bem como avaliar o potencial antibacteriano in vitro frente Staphylococcus aureus; Salmonella enteretidis;Escherichia coli e Pseudomonas aeruginosa e a atividade antifúngica in vitro frente o Fusarium graminearum.Os óleos e as cromatografias foram obtidos por hidrodestilação com parcerias externas. A atividade antibacteriana foi determinada por meio da microdiluição em caldo. Enquanto que a atividade antifúngica dos óleos de Baccharis dracunculifolia e Pogostemon cablin foi determinada por solubilização dos óleos no meio de cultura e dispondo um disco miceliar de F. graminearum. A atividade antioxidante foi determinada pela ação sequestradora do radical 1-difenil-2-picrilidrazina (DPPH). Como resultados obtiveram-se as constituições dos óleos essenciais principalmente por monoterpenos como 32,5% de cânfora no óleo de Rosmarinus officinalis, 47,0% de timol no óleo de Thymus vulgaris, 31,5% de patchulol em Pogostemon cablin; e ésteres como 40,1 % de acetato de lanalina no óleo de Lavandula angustifolia. Nos óleos das plantas nativas, a composição foi basicamente de sesquiterpenos como 17,58% de cis trans_nerolidol no óleo de Baccharis dracunculifolia, 31,6% de germacreno B no Hedyosmun brasiliense; 16,1% de α-selineno no óleo de Psidium guajava e 18,6% de α-bergamoteno no de Schinus terebinthifolius. A atividade antibacteriana do óleo de Thymus vulgaris, apresentou os resultados mais efetivos, com concentrações inibitórias mínimas (CIM) e concentrações bactericidas mínimas (CBM) de 0,195 e 1,56 µl/mL frente S. aureus; 0,195 e 50 µl/mL respectivamente para S. enteritidis; para E. coli a CIM foi de 0,390 µl/mL e CBM 0,780 µl/mL e para P. aeruginosa 0,780 e 12,5 µl/mL. As atividades antifúngicas foram determinadas frente ao F. graminearum tendo o Pogostemon cablin (8,0 µl/mL), no tempo 96 h inibido 80,0% do fungo. A atividade antioxidante do óleo essencial de Pogostemon cablin foi superior aos demais, com 12,08 µmol trolox/mL-1 de atividade sequestradora do radical. Sugere-se que os óleos de Lavandula angustifólia, Thymus vulgaris, Rosmarinus officinalis, Baccharis dracunculifolia, Psidium guajava e Schinus terebinthifolius, podem ser utilizados no combate de infecções causadas por S. aureus, E. coli, S. enteritidis e mais estreitamente por P. aeruginosa. E que o óleo de Pogostemon cablin possa servir como agente antifúngico frente ao fitopatógeno F. graminearum, além do óleo de Thymus vulgaris desempenhar importante atividade antioxidante. 2017-12-04T14:28:36Z 2017-12-04T14:28:36Z 2017-08-31 masterThesis LUCHESI, Luana Aline.
